It seems that more and more people justify investing in cryptocurrencies—even at current record prices—by claiming that they’re an effective hedge against the instability of fiat currencies.

But is it true?

Sure, a fiat money system where central banks can and do literally print money at will has its weaknesses. That’s why hard assets like gold are so popular among smart investors: as real stores of value, they provide a safety net against currency depreciation.

However, it’s doubtful that the same applies to cryptocurrencies. Despite what the crypto-evangelists will tell you, digital tokens will never and can never replace gold as your financial hedge.

Here are six reasons why.

#1: Cryptocurrencies Are More Similar to a Fiat Money System Than You Think.

The definition of “fiat money” is a currency that is legal tender but not backed by a physical commodity.

Since the United States abandoned the gold standard in the 1970s, this has been the case with all major currencies, including the US dollar.

Ever since then, US money supply has kept increasing, and so has the national debt. In contrast, the dollar’s purchasing power has been on the decline.

The huge spike in gold prices started right around the time when the Bretton Woods agreement collapsed in 1971 and US paper dollars couldn’t be converted to gold anymore. A clear sign of the decline in the dollar’s purchasing power since the move into a pure fiat money system.

It’s clear that cryptocurrencies partially fit the definition of fiat money. They may not be legal tender yet, but they’re also not backed by any sort of physical commodity. And while total supply is artificially constrained, that constraint is just... well, artificial.

Some countries are also exploring the idea of introducing government-backed cryptocurrencies, which would take them one step closer toward fiat-currency status.

As Russia, India, and Estonia are considering their own digital money, Dubai has already taken it one step further. In September, the kingdom announced that it has signed a deal to launch its own blockchain-based currency known as emCash.

So ask yourself, how can you effectively hedge against a fiat money system with another type of fiat money?

#2: Gold Has Always Had and Will Always Have an Accessible Liquid Market.

An asset is only valuable if other people are willing to trade it in return for goods, services, or other assets.

Gold is one of the most liquid assets in existence. You can convert it into cash on the spot, and its value is not bound by national borders. Gold is gold—anywhere you travel in the world, you can exchange gold for whatever the local currency is.

The same cannot be said about cryptocurrencies. While they’re being accepted in more and more places, broad, mainstream acceptance is still a long way off.

What makes gold so liquid is the immense size of its market. The larger the market for an asset, the more liquid it is. According to the World Gold Council, the total value of all gold ever mined is about $7.8 trillion.

By comparison, the total size of the cryptocurrency market stands at about $161 billion as of this writing—and that market cap is split among 1,170 different cryptocurrencies.

That’s a long shot from becoming as liquid and widely accepted as gold.

#3: The Majority of Cryptocurrencies Will Be Wiped Out.

Many Wall Street veterans compare the current rise of cryptocurrencies to the Internet in the early 1990s.

Most stocks that had risen in the first wave of the Internet craze were wiped out after the burst of the dot-com bubble in 2000. The crash, in turn, gave rise to more sustainable Internet companies like Google and Amazon, which thrive to this day.

The same will probably happen with cryptocurrencies. Most of them will get wiped out in the first serious correction. Only a few will become the standard, and nobody knows which ones at this point.
